HINGE.

SPECIFICATION forming part Of Letters Patent N0. 407,809, dated. J' Illy 30, 1889.

Application filed April 16, 1889. Serial No.307,395. (No model.)

To all whom. it r11/ay concern:

Be it known that I, XVILLIAM J. BODA, a citizen ot the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Hinges, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to an improvement in hinges for adjusting doors, and has for its object the improved construction ot such hinges.l

The novelty of my invention will be herewith set ortlnand specifically pointed out in the claims.

In the accompanying drawings, Figure lis a sectional plan through the rear or hinging end of a door, its jamb, and facing, showing the application of my improved hinge. Fig. 2 is a sectional elevation through the dotted line of Fig. l, looking in the direction of the arrow. Fig. 3 is an elevation of the half off the hinge which is secured to the door. Fig. 4 is an elevation of the half of the hinge which is secured to the jamb. Fig. 5 is an elevation of a portion ot' the rear edge ofl the door, showing the covering-plate. Fig. G is a detail plan view of one ot the fastening-lugs. The same letters of reference are used to indicate identical parts in all the figures.

A represents the rear or hinging side of a door, B the jamb to which it is hinged, and C the facing, extended in this instance beyond the jamb to afford a bearing for that part of the hinge which is secured to the jamb. The part of the hinge secured to the jamb consists of a flat back plate a, a rightangular fiat plate h, bearing against the rear side of the facing, and a projecting plate c in a plane parallel with the plate a and pro# vided with a central knuckle d. The rear side of the plate a has two or more, in this instance two, threaded or barbed lugs e, having tapering splits, as seen at f, Fig. 6, with the enlarged part of the split next to the plate, and having small circular openings g through the plate into said splits, as seen in Fig. 4. These lugs e are fitted into bores in the jamb, and pins h are driven through the openings g and, as the metal is usually wrought or malleable, serve to spread the lugs, as seen in Fig. 1, thereby effectually locking the plate a to the jamb. Ordinary Ascrews t' may be employed for securing the plate l) to the facing.

The outer half of the hinge upon which the door is secured and adjusted consists of a flat face-plate j in line With the plate b, and a right-angular portion k, lying upon the plate c and having end knuckles l, between which the knuckle d fits and is hinged by the usual pintle m. Upon the inner face of the plate jthere are three projecting lugs fn, n, and o. The outer ones nn have eyes p at their extremities, and, as seen in Fig. 1, I prefer to make them in two part-s screwed together to obtain adjustment for the eyes. The central lug 0 is fiat and has a slot q in its rear edge.

The face of the door has recesses r, Fig. 2, cut into it to receive the lugs n n o, and these recesses are sufficiently large to allow for the adjustment of the door, though they are at all times covered and concealed by the plate j. rlhe rear edge of the door has horizontal bores s s t, Fig. 2, opening into and through the recesses o and coincident with the lugs n, n,

and o, respectively. A screw u with an annular slot luis fitted into the bore t, and the slotted end of the lug o fits in this slot'c. Taper-screws w are inserted in the bores s s and pass through the eyes p, whose inner bores are made sharp, as seen at y, Figs. l and 3, to fit the threads of the screws '1o.

From this construction it will be seen that by first loosening the screws w and then turning the screw u the door may be adjusted so as to hang true and not bind, and, when so adjusted, byscrewing up the taper-screws w the plate j is firmly clamped to the door. For neatness of finish it is desirable to cover t-he bores s st with a covering-plate D, Figs. l and 5, which is held in place by wood-screws .a This plate of course has to be removed whenever it is desired to adjust the door.

The plurpose of making the eyes p adjustable is to enable them to suit any untrue boring of the bores s s, as will be readily understood.

Having thus fully described my invention, I claim- IOO be clamped by tapering` screws inserted in the rear edge of the door, substantially asdescribed.

3. A threaded or barbed fastening-lug for hinges, split up to the plate from Which it projects, and having an opening from said split through the plate for the insertion of a pin to spread the lug, substantially as described.
